Okay,
Original head gasket and original oil cooler (270,000km) - 2003 Discovery 2 Td5 ("facelift" model). Everything has been great, and still running with no issues at all, EXCEPT...
Checked fluids yesterday as I usually do most days and noticed there was a thin layer of engine oil floating at the top in the coolant header tank. Previously I had a very small coolant occasional drip/leak at the top front hose and someone suggested that was a sign of a blown head gasket (presuming exhaust gases in coolant and increasing pressure on hoses?). Anyway, I checked this same hose when running to see if it was rock hard as was suggested - it wasn't really - it would give when pressed (I used a rag so as not to get a burn).
So, runs fine - notice no difference when starting or running, but I obviously want to fix whatever problem I'm having! Original head gasket and original oil cooler. There is some coolant underneath the oil cooler and I believe there is a small coolant leak there.
Checked dipstick several times - oil is very clean, with no discolouration or no non-oil smell.
What do you think?
Any further checks I can do to narrow down the problem?
Once I think I'm on the right track then I'll need to order parts and work out what tools I will need to do either job - oil cooler or head gasket, or both?
Any thoughts?
